Last modified

CVE-2019-12254 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. In multiple Tecson Tankspion and GOKs SmartBox 4 products the affected application doesn't properly restrict access to an endpoint that is responsible for saving settings, to a unauthenticated user with limited access rights. Based on the lack of adequately implemented access-control rules, by accessing a specific uniform resource locator (URL) on the web server, a malicious user is able to change the application settings without authenticating at all, which violates originally laid ACL rules.. EPSS estimates a 1.15% chance of exploitation in the next 30 days.
